Device and method for producing environmentally-friendly revived rubber

Abstract

The invention discloses a process and a device for recycling waste rubber, in particular a device and a method for producing environmentally-friendly revived rubber. The device for producing the environmentally-friendly revived rubber is characterized in that: a heating device arranged on a plasticizing device is an electrical heating device; and two-screw conveyers are arranged in both the plasticizing device and a cooling device. The method for producing the environmentally-friendly revived rubber comprises: crushing the waste rubber into rubber powder, adding an active agent and environmentally-friendly oil into the rubber powder in a certain proportion, uniformly mixing the materials, heating the mixture in the plasticizing device electrically for plasticization, cooling the product of the plasticization to obtain plastic rubber powder, conveying the plastic rubber powder to a rubber rolling process, kneading the plastic rubber powder, and performing thin-pass refining to make rubber sheets. The method and the device for producing the environmentally-friendly revived rubber have the advantages of improving the mixing ratio of the conventional rubber plasticizing process, improving the quality of the revived rubber, effectively solving the problem that the rubber adheres on walls in production and conveying processes, recycling rubber volatile, saving energy and protecting environment.

Description

(1) Technical field [0001] The invention relates to a waste rubber recycling process and its device, in particular to a production device and method of environmentally friendly recovered rubber. (2) Background technology [0002] As an important strategic material, rubber is very important to all countries. my country is a big country that uses rubber, and the amount of waste rubber produced is relatively large. The country has been advocating, encouraging and supporting the production technology of waste rubber reuse and reclaimed rubber. , to solve the shortage of rubber resources in my country. At present, the desulfurization of reclaimed rubber mainly adopts dynamic desulfurization process, and its main disadvantages are as follows: [0003] 1. Secondary pollution: The dynamic desulfurization process must add a certain proportion of water in order to ensure the carbonization of rubber powder due to uneven heating. Water and regeneration agent react under high temperature...

AI Technical Summary

Problems solved by technology

[0003] 1. Secondary pollution: The dynamic desulfurization process must add a certain proportion of water in order to ensure the carbonization of rubber powder due to uneven heating. Water and regeneration agent react under high temperature conditions to produce a large amount of organic gas. The problem of secondary pollution cannot be fundamentally solved

[0004] 2. Poor safety: the current working pressure of the dynamic desulfurization process is 1.6-3.2Mpa and class II pressure vessels are required. Long-term use will cause the tank wall to become thinner and cause safety problems. Hidden dangers, improper operation will lead to equipment and personal accidents

[0005]3. High energy consumption: Due to the thick wall of the tank, the heat transfer speed is slow, the efficiency is low, and the energy consumption is high

[0006] 4. Unstable quality: Due to the large tank body, slow stirring speed, uneven mixing and fouling of the tank wall over time, the process is not easy to control. Uneven quality of desulfurized rubber material fluctuates greatly and is unstable
